Database db = Autodesk..ApplicationServices.Application.DocumentManager.MdiActiveDocument.Database;
      Transaction trans = db.TransactionManager.StartTransaction();
      try
      {
            BlockTable bt = (BlockTable)(trans.GetObject(db.BlockTableId, OpenMode.ForWrite));
            BlockTableRecord btr = (BlockTableRecord)trans.GetObject(bt[BlockTableRecord.ModelSpace], OpenMode.ForWrite);
            //Create the block reference...use the return from CreateEmployeeDefinition directly!
            BlockReference br = new BlockReference(pStart, CreatePolePedDefinition(pCellName));
            br.LayerId = CreateLayer(pLayerName);
            ObjectId newBtrId = btr.AppendEntity(br); //Add the reference to ModelSpace
            trans.AddNewlyCreatedDBObject(br, true); //Let the transaction know about it
            DBObject obj = trans.GetObject(newBtrId, OpenMode.ForWrite);
            XDataDispose.AddRegAppTableRecord("xlentComms");
            ResultBuffer rb = new ResultBuffer(
               new TypedValue(1001, "xlentComms"),
               new TypedValue(1000, pMslink + "," + pEntityNo)
            );
         obj.XData = rb;
         rb.Dispose();
         trans.Commit(); // Commit is always required to indicate success.
         Editor ed = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument.Editor;
         //db.SaveAs(ed.Document.Name, null);
         db.SaveAs(ed.Document.Name, true, DwgVersion.Current, db.SecurityParameters);
      }
现在要获取当前图中所有pLayerName

copy


Function GetLayers() As String()
       
        Using Trans As Transaction = DB.TransactionManager.StartTransaction
            Dim LayT As LayerTable = Trans.GetObject(DB.LayerTableId, OpenMode.ForRead)
            Dim ID As ObjectId, LayTR As LayerTableRecord, Lays As New List(Of String)
            For Each ID In LayT
                LayTR = Trans.GetObject(ID, OpenMode.ForRead)
                Lays.Add(LayTR.Name)
            Next
            Trans.Commit()
            GetLayers = Lays.ToArray
        End Using
    End Function

Database db = HostApplicationServices.WorkingDatabase;
         List list = new List();
         using (Transaction trans = db.TransactionManager.StartTransaction())
         {
               LayerTable layertable = (LayerTable)trans.GetObject(db.LayerTableId,
OpenMode.ForWrite);  //得到所有的层表
               if (layertable != null)
               {
                  foreach (ObjectId id in layertable) //遍历层表
                  {
                        LayerTableRecord tr=trans.GetObject(id,OpenMode.ForRead)
                  as LayerTableRecord; //获得层表记录
                        list.Add(tr); //将所有的图层放入一个集合中
                  }

               }
      }
   希望能帮到你！！！
